User Manual For - CONTROLLER/DATA RECORDER MultiCon CMC-99/141
7.15.
MODBUS
has one RS-485 port built-in. The
communication ability can be increased by installing a communication module into slot D of
the device (
). This module offers 2 additional serial ports (one RS-485, and one RS-
485/RS-232) and one ethernet port, which allows the creation of an advanced Multi-Modbus
system. In the current software version, a MODBUS RTU and MODBUS TCP/IP protocol are
available and every port can be switched to the Slave or Master (except port 4 which can be
only SLAVE) mode.
To establish a connection between MultiCon and another device using TCP/IP
protocol, port number 502 must be unlocked in the software and hardware firewall.
